Bruxelles Brussel 31-XII ENTOMOLOGIE 9 A NEW GENUS AND SPECIES OF APOLONIINAE (ACARI : TROMBICULIDAE) FROM SOUTH AFRICA WITH A KEY TO THE SPECIES IN THE SUBFAMILY (1) BY M. Lee GOFF (2) (With 1 textfigure) ABSTRACT Afropolonia tgifi, n. gen. & n. sp., is described from specimens taken from a rat, Aetbomys namaquensis, collected in South Africa. Examinaton of chiggers collected in South Africa by members of the Namaqualand Namibia Expediton of the King Leopold III Foundation for the Exploration and Protection of Nature has revealed a new monotypic genus of the subfamily Apoloniinae. The holotype is in the collection of the Institut Royal des Sciences Naturelles de Belgique, Brussels, and the paratype in the collection of the U. S. National Museum of Natural History (chigger collection currently housed at B. P. Bishop Museum, Honolulu, Hawaii). Ail measurements are given in micromètres. Terminology follows GOFF et al. (1982).

Results of the Namaqualand - Namibia Expédition of the King Leopold III Foundation for the Exploration and Protection of Nature (1980).

Holotype and 1 paratype from South Africa : Sturder Pass, ex Aethomys namaquensis (53 851), taken 4.X.1980 by X. MISONNE. R e m a r k s. VERCAMMEN-GRANDJEAN & KOLEBINOVA (1968) revised the Apoloniinae and proposed 2 tribes for the 7 species and 6 genera then recognized : Apoloniini and Sauracarellini. Subséquent to this treatment, VERCAMMEN-GRANDJEAN (1970 & 1971) described 2 additional species from Africa and Iran, and GOFF & LOOMIS (1982) described a species from the North Solomon Islands. Afropolonia is in the tribe Apoloniini as defined by VERCAMMEN-GRANDJEAN &c KOLE BINOVA, based on the unexpanded sensillae, along with Apolonia TORRES & BRAGA, 1938, Straelensia VERCAMMEN-GRANDJEAN & KOLEBINOVA, 1968, Vargatula BRENNAN & YUNKER, 1966, and Womersia WHARTON, Among these genera, Afropolonia is most similar to Straelensia in the form of the scutum and lacking subterminala, parasubterminala and microgenuala I, but differs in having the palpal tarsus 5BS (4BS for Straelensia), tibiala III present (absent in Straelensia), coxa II unisetose (bisetose in Straelensia) and lacking ventrolateral setae between coxae II and III (present in Straelensia). Afropolonia differs from Apolonia in having palpal tarsus 5BS (7BS in Apolonia), lacking subter minala I (present in Apolonia) and eyes free on cuticle (on ocular plate in Apolonia). Afropolina is similar to species of Vargatula in having palpal tarsus. 5BS, bt differs in having a nasus present (absent in Vargatula), coxa II unisetose (bisetose in Vargatula), and lacking both subterminala

$Afropolonia may be distinguished from the 2 genera in the tribe Sauracarellini, Sauracarella LAWRENCE, 1949, and Afracarella VERCAMMEN-GRANDJEAN & KOLEBINOVA, 1968, by having flagelliform sensillae$

Tibiala III is present in A. tgifi and Vargatula pacifica GOFF & LOOMIS, 1982, but is missing from Vargatula bispida BRENNAN & YUNKER, 1966, the other species in the genus Vargatula. Afropolonia may be separated from Womersia in having palpai tarsal formula 5BS (5B for Womersia), paired AM setae (single AM seta in Womersia), and lacking microgenuala I (present in Womersia). Afropolonia may be distinguished from the 2 genera in the tribe Sauracarellini, Sauracarella LAWRENCE, 1949, and Afracarella VERCAMMEN-GRANDJEAN & KOLEBINOVA, 1968, by having flagelliform sensillae (expanded sensillae in genera of Sauracarellini). In their treatment of the Apoloniinae, VERCAMMEN-GRANDJEAN & KOLEBINOVA included comments on Bernia marita ALLRED & BECK, 1966, which had been tentatively placed in the Apoloniinae by ALLRED & BECK (1966). Subsequently TANIGOSHI & LOOMIS (1969) noted that this species, represented by only the holotype, was actually an aberrant specimen of Hyponeocula arenicola (LOOMIS, 1954) and thus removed from the Apoloniinae.
